Posicionamiento del producto:
La barra colectora compuesta de interconexión principal de grupo a grupo de baterías HTD es un componente conductor de alto rendimiento diseñado para sistemas de almacenamiento de energía (ESS) a gran escala. Permite una interconexión confiable de alta corriente y convergencia de energía entre grupos de baterías paralelos. Construido con una estructura compuesta de cobre y aluminio (relación de volumen de cobre del 15% al 25%), equilibra una conductividad superior, un diseño liviano y una rentabilidad para la transmisión de energía a larga distancia. Utilizando tecnología avanzada de unión por rodillos, garantiza una unión metalúrgica con una resistencia al corte ≥35 MPa y un funcionamiento estable de -40 °C a 105 °C. Diseñado con geometría optimizada y aislamiento integrado, reduce la inductancia parásita a ≤15 nH, lo que aumenta la densidad de potencia, la seguridad y la eficiencia de los contenedores de almacenamiento de energía. Ideal para aplicaciones de almacenamiento industrial y de servicios públicos.
